Abstract. This paper is about adiabatic transport in quantum pumps. The
notion of ``energy shift'', a self-adjoint operator dual to the
Wigner time delay, plays a role in our approach: It determines the
current, the dissipation, the noise and the entropy currents in
quantum pumps. We discuss the geometric and topological content
of adiabatic transport and show that the mechanism of Thouless and
Niu for quantized transport via Chern numbers cannot be realized
in quantum pumps where Chern numbers necessarily vanish.
